  • the shell is then placed in a stereolithographic Process or in a laser sintering process a special granulate composed in several layers.
  • the volume required for the listener can therefore already be be taken into account when manufacturing the hearing aid housing 2.
  • the hearing aid housing 2 and the fastening means for the receiver 1 in the hearing aid, in particular a cavity forming wall 2A are integrally connected to each other and can be produced in the same manufacturing process.
  • the receiver 1 has a sound transmission port on its front side 3 on. This forms the sound outlet opening 4 of the handset 1. On the front of the handset There is a nozzle on the opposite rear of the housing 5. Its outer shape is consistent in the exemplary embodiment the outer shape of the sound passage 3 match.
  • the Stub 5 is also tubular and serves Implementation of the electrical connection lines 6 of the receiver 1.
  • the elastic holding elements 7A and 7B are on the front of the housing and on the back of the receiver 1 elastic holding elements 7A or 7B arranged.
  • Point for attachment with the handset 1 the elastic holding elements 7A and 7B corresponding to the outer shape of the sound passage connector 3 or the connector 5 negatively shaped openings on it, making them easier in Way can be plugged onto the nozzle.
  • For additional Fixation serve on the sound passage 3 and beads 3A or 5A formed on the connection piece 5.
